| EEVblog #751 - How To Debunk A Product (The Batteriser) |
| << < (17/1798) > >> |
| Mr Simpleton:
Running a battery at 100 mA and 1.5 volt down to say 1V then put the gizmo on... means you will take 150 mA (in a perfect world) out of the poor battery, which is depleted already. With increasing Ri this thing will go down hill real fast :-DD |

There is no significant time curve dip below 1V, down to 0.7V. The internal battery resistance doesn't increase until below that voltage. |

The battery manufacturers are well aware of the wasted energy in their product and how to recover some of it. --- End quote --- We all agree that some additional energy can be squeezed out of batteries with a boost converter. Would such a converter achieve any significant gain for the user ? Simple technical considerations show that no, unless we talk about some very rare badly designed products. Therefore their claims are false and the end-users will never get what is advertised to them. This is the definition of a scam. In the same way, the "white van" audio system does produce sound. Does it meet its high fidelity claims ? No. Same thing. With Batteriser, the scam is even more elaborated because their real target are probably the silicon valley investors. |
| Wytnucls:
I wouldn't call a probable 20% gain for most devices insignificant. Your technical considerations are based on flawed principles, like battery voltage that can't be used below 0.8V coupled with supposedly high battery internal resistance. |
